Benefits of technology

"The present invention is a micro USB socket connector that includes a metal casing and a plastic core member with metal terminals embedded in it. The plastic core member is held in position by constraint devices on the metal casing and the extension arms on the plastic core member. The metal casing also has grounding strips for excellent grounding function. The connector can be used for attaching to a circuit board or for holding down the plastic core member. The technical effects of the invention include improved reliability, durability, and secure grounding function."

Problems solved by technology

After a certain number of times in plugging and unplugging, both the connection between the metal casing and the circuit board and that between the plastic core member and the metal casing may be loosened, resulting in a connection error.

Embodiment Construction

[0031]Referring to FIGS. 1˜3, a micro-USB socket connector in accordance with a first embodiment of the present invention is shown comprised of a metal casing 1 and a plastic core member 2.

[0032]The metal casing 1 is a hollow metal holder member having a front open side and a rear open side. The plastic cover member 2 is insertable through the rear open side into the inside of the metal casing 1. The metal casing 1 has a first constraint device 11 at one of the top and bottom walls thereof, for example, at the top wall, two rear extension arms 12 at two opposite lateral sides of the first constraint device 11. According to this embodiment, the first constraint device 11 is a notch at the rear side of the top wall of the metal casing 1. The front open side of the metal casing 1 is adapted for receiving a micro USB plug connector (not shown).

[0033]The plastic core member 2 is an electrically insulative block member having a plurality of metal terminals 21 molded therein. The plastic c...

Abstract

A USB socket connector includes a plastic core member, which has metal terminals embedded therein and a constraint member, for example, a raised portion, and a metal casing, which houses the plastic core member and has a constraint device, for example, notch that receives the constraint device of the plastic core member to hold the plastic core member in position upon insertion of the plastic core member into the casing, and two rear extension arms that are bent into shape and stopped against the back side of the plastic core member to hold down the plastic core member firmly in place after insertion of the plastic core member into the metal casing.

Description

BACKGROUND OF THE INVENTION[0001](a) Field of the Invention[0002]The present invention relates to a USB (Universal Serial Bus) connector and more particularly, to a micro USB socket connector, which comprises a plastic core member having multiple metal terminals embedded therein and a metal casing that houses the plastic cover member, wherein the plastic core member has a constraint device, for example, a raised portion forced into engagement with a matching constraint device, for example, a notch of the metal casing, and the metal casing has two rear extension arms bent inwards or downwards to hold down the plastic cover member.[0003](b) Description of the Prior Art[0004]A micro USB (Universal Series Bus) connector has a dimension smaller than a mini USB connector. Micro USB is a new generation specification of mini USB, having a dimension reduced by 60% when compared to mini USB. For the advantages of lower profile and high power characteristics, micro USB is practical for use in ...
